Density of Wind-Blown Sand Measured by Immersional Wetting and Ring Sampler

浸水+环刀法测定干燥风积沙密度

The sampler was immersed in the liquid by lifting the central rod through the upper ring.

通过取样器上端的环提起中心杆使取样器浸入液体中.

The method which soaks the wind-blown sand before measuring the density by ring sampler is introduced.

本文介绍的方法是通过浸水润湿风积沙,再用环刀法测定密度.

Contrast Test of Reinforcement Penetration Method and Ring Sampler Method for Sand Filling Compactness

填砂密实度的钢筋贯入法与环刀法对比试验

To improve efficiency and veracity of soil sampling in testing bulk density, the cutting ring method and in situ soil tube method were combined and a multi-segment in situ soil sampler was designed.

为了提高土壤容重测定中土样采集的效率和精准性，将环刀法和原状取土管法结合，进行了分段式原状取土器的研制。
